leaflet.draw 踩坑

1、官网api中修改toolbar的文字为

var modifiedDraw = L.drawLocal.extend({
          draw: {
            toolbar: {
              buttons: {
                polygon: '添加一个多边形'
              }
            }
          }
        });

浏览器报错："TypeError: L.drawLocal.extend is not a function" 查询github的issue得到解决方案： L.drawLocal.draw.toolbar.buttons.polygon="绘制面"

真的好奇怪，2017年有人提出的问题，官方到现在都没有修改api文档，乌鸡鲅鱼。。。。

2、浏览器报错 Cannot read property 'hasOwnProperty' of undefined

翻了好久的github，终于找到原因 Prevents calling setStyle with undefined argument by same31 · Pull Request #952 · Leaflet/Leaflet.draw · GitHub

leaflet.draw.js中找到 poly.setStyle(poly.options.editing) 改成

if (poly.options.editing) {
    poly.setStyle(poly.options.editing)
}
